Abstract

Superwettability controlled overflow is presented. Superhydrophilicity enhances overflow and superhydrophobicity reduces overflow. The fundamental mechanism for the dynamic interaction between fluids and solid-edges is revealed and several methods for preparing the surfaces of solid-edges with superwettabilities are presented. The insights gained provide new opportunities to achieve controllable dynamic interaction at solid-liquid interfaces for various applications.
